[Bug libstdc++/27904] operator>> to floating point variable does not support "inf", "infinity", or "nan"

In C90 strtod does not say anything specifically about "inf", etc.  However, it
does say:

In other than the "C" locale, additional implementation-defined subject
sequence forms may be accepted.

In any case, to me this is a quality of implementation issue.  A good
implementation will accept "inf", "infinity" and "nan".  The fact that C99
explicitly accepts them seems sufficient justification to me.  If necessary we
can act otherwise if POSIXLY_CORRECT.
